Great value for the money, definitely recommended!
If you are familiar with a solid automated home that uses zegbee2mqtt, you can take it off the market or get discounts without risk.
Pros
Fantastic in z2m. Whistle CC2538+CC2592, IoT - Iobroker is what I use. I exclusively use direct connections with the fastest reaction times; I don't use any Chinese, European, or other hubs. A control signal for on/off and the amount of electricity used are sent to Zigby. For a month and a half, there were no failures or losses. It can, of course, operate in repeater mode.
